Faraday optical isolator in the 9.2 $\mu$m range for QCL applications

Laurent Hilico, Albane Douillet, Jean-Philippe Karr +1

We have fabricated and characterized a n-doped InSb Faraday isolator in the mid-IR range (9.2 $\mu$m). A high isolation ratio of $\approx$30 dB with a transmission over 80% (polarize…
